This isn't the first report of a domestic disagreement potentially causing the couple's split. Almost immediately after the breakup was announced, a source told British tabloid The Mirror that, "[Brand] wanted [Perry] to stay at home, do the whole Hollywood housewives thing. But that was never going to happen for Katy, she loves her singing career."

Perry and Brand may have even alluded to the reported dispute themselves in separate, pre-split appearances on "The Ellen DeGeneres Show." In November 2011, shortly after the pair celebrated their one-year anniversary, Perry told the talk show host that she believed having children was "one of the reasons you get married," but admitted that she wasn't "sure it's time yet." A month later -- and mere weeks before he filed for divorce -- Brand was quizzed on the subject of babies during his appearance on the show. "I would like one," Brand replied. "I love those little babies in the beginning... They're so lovely in that bit."
